Technical Specifications

Protective Sealant

EPP-918A Protective Sealant is a liquid applied protectant designed to improve the durability and reliability of RJ11 and RJ45 modular jacks. It helps prevent corrosion from harsh environmental conditions, withstands high temperature soldering (in excess of 260 C for 10 seconds), and maintains low contact resistance through 10K cycles. The sealant contains a UV tracer for visible inspection and adheres instantly without migration. It is RoHS compliant and compatible with virtually any Stewart connector product.
